FUEL-MIXING nnvron.

Specification of Letters Patent.

Application filed February 18,1918.. Serial No. 217,897. e

connection with gas burners, whereby the" latter will be rendered more efficient from a stand point of heat production and fuel consumption, and to permit of a constant and regulated flame through the provision of improved mechanism which is utilized to supply the burner with a steady and uninterrupted stream of fuel. 7

It is within the province of the inventionto improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view, which will appear as the descriptlon proceeds, the invention resides in the combination and arrangement of parts, and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawing;

Figure 1 is a side elevation of the fuel commingling device comprising the present invention.

Fig. 2 is a vertical sectional view thereof.

Fig. 3 is a transverse sectional view taken along the line 2-2 of Fig. 1.

In the accompanying drawing the numeral 1 indicates a fuel supply pipe, which is supported within'brackets 22, one end of the pipe being closed and the opposite end threaded, as at 3 for connection with a suitable form of valve 4, any preferred means being provided for admitting gas or other similar fuel to the valve 4. In this instance the valve .is provided with a plug 5, and is formed with a port 6 for controlling the flow of fuel through the valve structure and into the supply pipe 1. Spaced outlet jets 7 are carried by the outlet pipe, and are formed with centrally disposed, relatively restricted passageways, through-which the fuel flows from the pipe 1,- ina thin stream.

Carried by the bracket'sQ is a frame 8 which is utilized to support a longitudinally extending, hollow fuel mixing receptacle 9,

and the latter is provided with vertically extending inlet tubes 10, which are preferably located in vertical alinement withthe jets 7, the lower ends'of fthetubes 10 being slightly spaced, vertically, from said .jets so that gas passing upwardly within the tubes .may be mixed with-air, .1 drawn into said tubes from the space existing between the jets and the lower ends of said tubes.

Theupper ends of the tubes 10 terminate just short from the sidev of the receptacle 9 opposite to that to which they are connected, so that the gas and air will be permitted to circulate within the hollow interior of the receptacle 9. Located on opposite sides of the tubeslO, and preferably extending in parallel relation therewith, are a plurality of outlet tubes 11, which latter extend into the receptacle and terminate adjacent to that portion of the receptacle through which the tubes 10 are adapted to pass, this construction results in spacing the inner ends of the tubes 10 and 11, so that the same will be relatively offset. The tubes 11 are adapted to communicate with any suitable form of gas burner (not shown). It will be understood that any suitable means may be provided for securing the tubes 10 and 11 in fixed positions within the receptacle 9, such as by use of solder or screw threads or the like. X

From the foregoing description taken in connection with the accompanying drawing it will be seen that fuel passing through the mixing structure described will be thoroughly commingled with air drawn into the same, so that a highly combustible mixture may be obtained at a gas burner connected with the structure. This is produced by permitting the gas to circulate in a circuitous manner within the receptacle 9, so

that the fuel particles will have ample opportunity to become thoroughly commingled before being discharged from the tubes 11. Through the provision of the hollow interior of the receptacle 9, the flow of fuel through the tubes 11 will be effected in a steady and regulated manner, and with total absence of fluctuation or wavering qualities. I claim: e v 1. A fuel commingling structure for'gas burners, comprising a fuel supply pipe, an outlet opening in said pipe, a mixing receptacle disposed in cooperative relation with said pipe, an inlet member carried by said into said receptacle and spaced a considerable distance beneath the inner extremity of said inlet member whereby a fluid circulating through said receptacle will flow a circuitous path.

2. A fuel commingling structure for gas burners, comprising a fuel supplying element, restricted outlet jets protruding from said element, a fuel commingling receptacle, inlet tubular members carried by one side of said receptacle and disposed substantially in alinement with said jets but terminating in spaced relation therefrom, the inner ends of said member extending into the hollow interior of said receptacle and terminating adjacent to that side of the latter opposite to which the tubes enter, and a plurality of outlet members having the inner ends there of disposed within said receptacle and terminated adjacent to that side of the latter through which the inlet members protrude, whereby a fluid circulating through said receptacle will flow a circuitous path.

In testimony whereof I affix my signature.
